Description
The OPF522 contains a monolithic
photo-IC comprised of a photodetector
and DC amplifier driving an open
collector output Schottky transistor. The
output makes the OPF522 compatible
with TTL and CMOS logic.
The receiver is designed to operate from
a single +5V supply. It is essential that a
bypass capacitor be connected from VCC
to Common of the receiver.
This component is susceptible to damage from electrostatic discharge (ESD). Normal
static precautions should be taken in handling and assembly of this component to
prevent ESD damage or degradation.
